Museums, nightclubs and karaoke bars have closed in and around South Korea’s capital, Seoul, as Covid-19 cases reach a five-month high.
The country reported another 297 new cases – the highest daily figure since March.
South Korea is viewed as one of the world’s coronavirus success stories for its management of the disease.
But a spike in new cases linked mostly to a church has sparked concerns of a wider outbreak.
Wednesday saw a three-digit increase in cases for a sixth day after weeks with numbers generally around the 40s. Of the 297 infections reported, 252 were in the greater Seoul area.
Many of the new cases have been linked to the Sarang Jeil Church, whose pastor has been a vocal critic of President Moon Jae-in.
